Observation details testicular microliths' effects on semen quality in dogs, suggesting potential implications.
Testicular microliths are small areas of calcification in testicular tissue, identified ultrasonographically as diffuse, punctate, nonshadowing, and hyperechoic foci. Poor semen quality is associated with increasing numbers of testicular microliths in humans. There is much less description of this phenomenon in animals; we are describing 2 dogs that had microlithiasis.
